Forensic genealogy to identify criminal offenders through GEDmatch and related databases would be prohibited in Maryland, according to the intent of a new bill pending in that state's legislature.

A revolutionary drug test can detect amphetamines, cannabis, cocaine and opiates from the sweat of single fingerprint sample in just 10 minutes. The research shows that the technology works on both the living and deceased.

An influential state commission issued a highly critical assessment on Friday of a second key player in the murder conviction of Joe Bryan, saying a Texas Department of Public Safety crime lab chemist had “overstated findings, exceeded her expertise and engaged in speculation” when she testified in 1989.

In a Tuesday evidentiary hearing in a cold case murder investigation, the defense focused on the professional credibility and integrity of a former Delaware State Police forensic firearms examiner facing an unrelated trial next month for allegedly falsifying his time sheets in 2016 and 2017.

Police departments have been scrambling to keep up with all the shootings around the Puget Sound area over the past week. Some departments may send evidence left behind by the shooters to the Washington State Patrol crime lab - evidence that's almost as valuable as a fingerprint.

The expert whose testimony was key to Bryan’s conviction for his wife’s 1985 murder says he now believes that some of his techniques were incorrect. His admission comes as a judge considers whether Bryan, whose case was the subject of a ProPublica and New York Times Magazine investigation, should get a new trial.

An influential state commission said the blood-spatter analysis used to convict a former Texas high school principal of murdering his wife in 1985 was “not accurate or scientifically supported” and the expert who testified was “entirely wrong.”
